Dimension comparison
Overview of the Angle Grinders
When comparing the AVID POWER Angle Grinder and the DEWALT FLEXVOLT ADVANTAGE 20V MAX* Angle Grinder, there are substantial differences that cater to varying user needs. The AVID POWER model is priced at $56.99, making it about 17% cheaper than the DEWALT model, which retails for $144.50. This price difference reflects a significant gap in features and capabilities, as both tools are designed for different types of users and applications.
Power and Performance
The AVID POWER Angle Grinder is equipped with a powerful 1,000W motor that reaches no-load speeds of 3,000 to 11,500 RPM, which is suitable for a variety of cutting and grinding tasks. In contrast, the DEWALT FLEXVOLT ADVANTAGE's brushless motor delivers 1,550 max watts out, allowing it to achieve speeds of up to 9,000 RPM. This means that while the AVID POWER grinder offers higher RPMs, the DEWALT provides more overall power, especially when paired with a FLEXVOLT battery. Users looking for maximum capability in tougher applications may find the DEWALT model more appealing.
Features and Usability
The AVID POWER Angle Grinder boasts seven variable speeds, providing versatility for various cutting and grinding jobs. Its paddle switch with a lock-on button enhances user comfort, allowing for extended use without fatigue. On the other hand, the DEWALT model includes advanced safety features like a kickback brake and E-CLUTCH system, which quickly shut down the motor in case of a bind-up, significantly enhancing user safety. The DEWALT also offers Tool Connect Chip compatibility for asset management, appealing to professionals who need to track equipment on job sites.
Design and Build Quality
Both grinders are designed with user comfort in mind, but they approach it differently. The AVID POWER grinder features a non-slip rubber grip that reduces vibration, making it more comfortable during prolonged usage. Additionally, the integrated spindle lock allows for easier wheel changes. Conversely, the DEWALT grinder's design emphasizes safety with its E-Switch Protection, which requires the trigger to be cycled to restart after an unexpected shutdown. This feature, combined with a durable build, makes the DEWALT grinder a robust option for heavy-duty tasks.
Included Accessories
The AVID POWER Angle Grinder comes with a comprehensive package that includes two cutting wheels, two metal grinding wheels, a lock nut wrench, and a side handle, providing great value for its price. In contrast, the DEWALT model is sold as a tool-only option, meaning users will have to purchase batteries and chargers separately. This can lead to additional costs, making the initial investment significantly higher for the DEWALT grinder. For users who need a ready-to-use package, the AVID POWER grinder offers greater convenience right out of the box.
Sales Rankings and Market Position
The AVID POWER Angle Grinder has a bestseller rank of 28,013, while the DEWALT FLEXVOLT ADVANTAGE ranks higher at 14,755, indicating a preference among consumers for the DEWALT model. This could be attributed to its advanced features and the brand's reputation for quality and performance in professional settings. Users looking for a grinder that is widely adopted in the market might lean towards the DEWALT option, despite its higher price point.
User Safety and Protection Features
Safety is an essential consideration when choosing an angle grinder. The AVID POWER model includes a wheel guard to protect users from sparks and debris, along with a design that keeps the cutting wheel away from the user. The DEWALT grinder goes further with its kickback brake and E-CLUTCH features that offer maximum protection in hazardous situations. These safety enhancements make the DEWALT grinder a preferable option for users who prioritize safety in their work environment.
Which should you buy?
Choosing between the AVID POWER Angle Grinder and the DEWALT FLEXVOLT ADVANTAGE largely depends on your specific needs and budget. The AVID POWER model is an excellent choice for casual users or those on a budget, offering adequate power and features at a significantly lower price of $56.99. However, for professionals or those who require a more powerful and feature-rich tool, the DEWALT grinder, priced at $144.50, is likely the better investment due to its superior performance, safety features, and compatibility with advanced battery technology. Ultimately, your choice should align with how you plan to use the grinder and the level of durability and safety you require.
